1N5350CE3/TR13

Overview

The Microchip Technology 1N5350CE3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 14V with a ±5% tolerance, indicated by the 'B' suffix. The device operates in an axial DO-201 package and features a maximum dynamic impedance of 2.5 ohms at a test current of 100mA. It withstands a maximum regulator current of 670mA and surge currents up to 10.6A. The component is RoHS compliant (e3) and supplied in tape and reel packaging (TR13).

Feature Summary

• Provides stable voltage regulation across a broad operating current range.
• Withstands high surge stresses and steady-state power dissipation.
• Features flexible axial-lead mounting terminals for through-hole integration.

Applications

• Voltage regulation circuits requiring 5W power handling.
• Power supply protection against transient overvoltages.
• Reference voltage generation in electronic systems.

Procurement Notes

Verify the specific ordering suffixes to confirm compliance requirements and packaging format. The e3 suffix indicates lead-free construction, while TR13 specifies tape and reel delivery. Confirm that the manufacturer designation aligns with current corporate ownership structures following industry acquisitions. Ensure the component meets the required environmental screening levels for the intended application environment.

Selection Notes

Select this component when a 14V regulation point is required within a 5-watt power envelope. The axial leaded package facilitates manual assembly or standard through-hole manufacturing processes. Consider the thermal resistance characteristics and derating curves if the ambient temperature exceeds standard limits. Verify that the dynamic impedance and knee current specifications meet the circuit's regulation accuracy requirements.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series covers a wide voltage range from 3.3V to 200V in a standardized 5-watt axial package. These devices are widely used in industrial and commercial electronics where robust voltage clamping and regulation are necessary.

Replacement Considerations

Cross-reference with other manufacturers offering 1N5350 equivalents in the DO-201 package. Verify that substitute parts match the 14V nominal voltage, 5W power rating, and ±5% tolerance. Ensure the replacement maintains similar thermal resistance and surge current capabilities for direct board compatibility.
